The latter moves freely upon the guide 13, which is pert of the Vibrating frame A B, aindis planed true to nev 3 G is. an eccentric, fastened to the haft 0, and H is a yoke embracing it, and pivoted at its lower extremity t th base A, 0 0 SOIDB {fixed part thereof, The upper end of this yoke is connected to the frame A B, in such a mannm as to allow it to have 5; slight vertical and ml-ling movement th re n, as indi t y the ;slot 3 Fig. 2, and as the shaft 0 revolves the eccentrie impair-ts 31 vibmh Qil 1 t h me, as d ceted in Fig. 2, by fell and dotted lines.

P of s movement except at the upper, end the binding-arm eonsequently held rigidly when aeting on the grain,

*It will "be nbserved that by this construction the 1 extremity of the binding erm derives a peculiar eompenml mosemen simi r 0 that of the human arm, in encirciin g a gavel of grain for the" P11 11 59 0f bill i l g- The twisting and wine-cutting devices are located an the. vibrat ng ame A B, n i e with thevertical movement of the bindingarm, Fig. 1, and are act at d y mutilated gears J J en the shaft 0.

The gear .J operates two pinions land m, Figs-1, 3, 6, and 7, lbei g f st to the smell vertiealshaft n, Fig. 3, end m to the tubular shafto, concentric with n, as indicated. To

the other extremities of n and o are secured,

respectively, the plate 1) and hook r, the shape and relative position of which, when at rest, are shown in Fig. 4..- Th p a p s a c 1 m, and the heck r is so formed that when it revolves it gathers the wire into said notch. A lip, d, Fig. 8, is secured to the lower side of 10, between which and the latter the hook r enters a short distance. The wire is thus kinked and clamped tightly, as shown.

Pinions l and m are moved as one pinion by that complete portion of the gear J marked h in Fig. 3, and consequently the hook 'r and plate p revolve together. The segment 2' moves only the shaft 0 and hook, while segment j only moves the plate 1) and its shaft. The pinions are held in a stationary or locked position by means of flanges f g 0 formed upon the gear J, inside and outside of the teeth, which flanges are turned true and bear against projecting hubs s t, which are correspondingly flatted, as shown in Figs. 6 and 7, s, (11113011 one side only, and t upon two opposite s1 es..

K, Figs. 1, 3, 4, and 5, is the wire-cutter and clamp, located directly under the twister-hook r, and arranged to oscillate between two fixed jaws, a. b. These latter are recessed, as shown in Fig. 5, and the cutter K, which cuts upon either edge, swings a short distance into the recesses, the under edges of the jaws and the upper edges of the knife forming shears, which operate in either direction. An arm of the cutter' K extends back of the twister, and preferably around the shaft 0, and is given a single reciprocation upon the pivot c at each revolution of the shaft 0 by means of the vertical crank-shaft w, pinion y, and segmental gear J, which is secured to the shaft 0 or to the back of the gear J. The teeth of the pinion 3 are cut away upon opposite sides, as shown in Fig. 9, and starting pins or lugs 2 project from its hub just above the periphery of J, the pin it upon the latter coming in contact with them at the proper time to bring the teeth of each segment of the pinion into mesh with the segment '0 on the gear alternately.

The lower edges of the cutter K are rounded, together with the contiguous edges of the jaws a b, as indicated-in Fig. 5; and it will be seen that, as the wire is caught in the shear, that portion above the cutter will be severed, while the other portion will be pinched between the rounded corners or edges of the cutter and jaw, and securely held there.

The operation of my invention is as. follows: Wire from a spool suitably supported is passed through the eye of the bindingarm, as shown in Fig. 2, and the latter is then made to descend by revolving shaft 0, passing through, in the lower portion of its movement, a slot in the receiver 1, and bringing the projecting end of the wire between the jaws a b. By the completion of the revolution of G the cutter K is thrown over to the opposite extremity of its movement by means of"1the segment 0, thereby -cutting 01f the waste bit of wire and clamping the end. The machine is now ready for binding. As the motion of G continues the binding-arm ascends, and in again deseendingpasses around the gavel of grain lying in thereceiver I, compressing it against the loop of wire, and bringing the latter, now double, down to the position shown in Figs. 3 and 4, between the cutting-jaws a! b, and into the notch 12 in the plate 12. At this juncture the segmenti on the gear J gives the hook 4' half a revolution, catching the doubled wire and clamping it in the notch '12, as indicated in Fig. 8. The cutter K now makes its movement, the segment '1; on J being timed between the portions iand h on J, as indicated by dotted lines in Fig. 3. This releases the clamped end of'the wire, cuts the doubled wire, and again clamps the end projecting from the binding-arm. Segment h now twists the ends of the band, they being securely held by the jaws p r d, at the close of which the segment j gives plate 19 half a,turn, hook 1' being held by the flange 0, thus opening the twister and allowing the bundle'to dropofi' the binding-table. The parts are then in a position ready for the next gavel; I

It will be observed that. theoseillation of the frame A B does not afiectlthe operation of the gearing upon the shaft .;O,;such vibration being concentric therewith. 1

To insure the catching of thcwires by the hook r, it will be found advantageousv to provide a notch, t, Fig. 3, in the binding arm, through which the point of the hook passes,

picking up the wire which liesjagainst the 7 face of the binding-arm, as shown.

The cutter K need not be made with two cutting-edges; but I prefer that construction.

By giving the crank-shafta; anentire revolution the cutter will make a rdouble reciprocation, and perform the cutting and clamping v operations upon one side only, in; connection with a single jaw, a.

It may be found advisable to use a cam in place of the crank D, so as: to give the binderarm a rest at the upper or lower extremities of its stroke, or both. By thismeans the frame A may swing over before the binder-arm be gins to descend, and when the latter is clear 7 down a short interval of rest gives the twister timetooperatc. What I claim as my invention, and desire to secure by Letters PatentJs-j- 1. In combination with the concentric twister-plate p and hook r,and the pinions l and m, the mutilated gear J, the latter having a continuous rotary motion, and formed substantially as shown and described, for the purpose of imparting to said twistenplate and hook unlike intermittent rotations, always in the same direction, as and for the purposes set forth.

2. In combination with thecutter K, the segmental gear J, crank-shaft w, and connected parts, arranged to operate substantially as set forth.

3. The binding-arm F, having a vertical movement upon a guide, B, a lateral move twisting apparatus 11 r, and clamping wirement with its supporting-frame, and an, upcutter K, substantially as and for the purposes upward swing by means of the rook-shaft b set forth.
